Social-software iMproving wARfarin Therapy (SMART)
Randomized Evaluation of Social-software Improving Warfarin Therapy in Patients With Mechanical Heart Valve Replacement
연구 개요
상세 설명
Social software is becoming a necessary of life. Wechat, powered by Tencent company, is the most popular social software in China. People can chat with others no matter how far away from each other.
Anticoagulation Quality is very important for patients receiving warfarin anticoagulation therapy, which is usually evaluated Time in therapeutic range (TTR). It is reported that TTR is very low (38.8%) in China patients. So we are planning to introduce the social software to set up a bridge for clinicians and their patients, to instruct warfarin therapy. We aim to investigate whether social software could be used to improve warfarin anticoagulation quality of Chinese patients.
We planned to enrol enough eligible patients receiving warfarin therapy due to the mechanical valves in a randomized controlled trial. Warfarin-treated patients were assigned to social software management group ( in which warfarin therapy was guided via the social platform by experienced clinicians) or to the traditional management control group (in which warfarin therapy was managed with traditional model). The primary outcomes the first time to bleeding or thrombotic events, the secondary outcomes were an elevation in time in therapeutic range (TTR) of international normalized ratio (INR), reduction in INR variation and number of extremely high INR results during 18 months.

실험적: Social-software management group
We set up a mini-program based on wechat application.
We instruct warfarin therapy via social-software including dose adjustment, answer questions, remind monitoring INR et.al.
|
Using Wechat application, a social platform, to manage warfarin therapy in patients with mechanical valve replacement.

간섭 없음: Routine management group
This is the control group, Warfarin therapy was managed via traditional style without social software intervention.
